Problem Scenario
Broad Question
Specific Question:
Does the Wood Type effect Heat Temperature produced?
Hypothesis:
It all depends on the wood . Wood will burn longer and put off a hotter temperature depending on the wood type. I think maple will burn the hottest.Graph of Hypothesis:
Variables
Independent Variable:Wood Type
Dependent Variable: Heat (Celsius)
Variables That Need To Be Controlled: Amount of Wood, Wood Moisture Content
Vocabulary List That Needs Explanation
General Plan
Several species of wood will be burnt for 180 seconds under a fume hood to heat up water. The water temperature will be monitored to see how much Heat is put off by each Wood Species. From there I will repeat each Wood Species twice. I will do my data analysis to determine which wood will produce the most heat.Potential Problems And Solutions
Wood not burning-get dryer wood.Safety Or Environmental Concerns
Smoke. Setting something on fire.
Experimental Design
(add the correct headings from the experimental design page before beginning)Resources and Budget Table
Detailed Procedure
1. I will take each species of wood and burn them 5 different times.2. I will put a beaker with 50 ML. of water above my small fire. I will be working in a [[#|fume hood]].
3. I will put a Temperature Probe in the water and it will be hooked up to a computer to record the temperature and heat energy produced.
4. I will repeat this with each species two times.

Results
My results are that Maple puts off the most Heat for a 180 Second Trial. Maple burnt to 45.7° C. The Second best wood was the Oak that burned to 44.7° C. I thought I got pretty accurate results considering my hypothesis.Conclusion
My hypothesis was that wood would burn hotter and better depending on the species. I found that my hypothesis was true. Maple wood burnt the best and hottest for 180 seconds. This is what I expected, but I was not so sure. I thought dryer wood might burn better, but not hotter. I was pretty accurate. This is the final results of my 2013 Science Fair Experiment.Discussion
I found in my experiment that Maple burnt to the hottest temperature. The hard wood burnt hotter than the soft wood did. That goes along with what I predicted. There was a strong relationship between my independent and dependent variable. The Wood type does matter on the effect of heat produced. The harder the Wood the better it would burn and it would last longer and burn hotter. I had a problem of the birch not burning as well as the rest, but I solved it and it turned out alright. Next time I would try to get a better variety of wood and try to get it really dry. For the most part, this project worked out well.Benefit to Community and/or Science
This Science Fair Project could benefit to the community in several good ways. This tells people who have a Wood Stove or Furnace what types of wood are worth your while buying or processing themselves. Some places who sell cut firewood might sell pine, which isn't a great quality wood. It is cheap to get and doesn't burn as good as oak or maple would burn, to provide more heat energy.Background Research
Wood has many different textures. Smooth, rough, or jagged. Wood has different bark types such as leafy, hard, rough, or prickly. Bark is very important to a tree. The bark is a protective layer on the exterior of a tree's stem, focused to protect internal parts. Bark also is a food for animals such as Deer. Bark can also make wood burn differently. The Bark could provide for a good fire starter or not so much.References
Abstract
I have completed a Science Fair Project on Wood Burning Temperatures. My intention was to find which Wood Species burnt to the highest temperature. I found that Maple burnt to the highest temperature. That was what my hypothesis was. I started my cutting some wood at home. I cut Maple, Oak, Spruce, and Birch. I cut them to small pieces and burnt them in a Fume Hood. I analyzed my data and came to a conclusion about my project.
